About Submer

Submer designs and delivers end-to-end AI datacenter infrastructure built around industry-leading liquid cooling.

We help organizations scale AI beyond the limits of traditional datacenters by enabling higher density greater efficiency and lower environmental impact accelerating time-to-AI from first deployment to full production.

What impact you will have

The Product Line Owner is the end-to-end business leader for a product line of high-density cooling racks for AI and high-density compute. Acting as a mini-GM the PLO owns market insight product strategy roadmap and financial performance (P&L) from concept to end-of-life. The role combines deep technical understanding of liquid cooling and high-density AI infrastructure with strong business negotiation and stakeholder-management skills ensuring the product line delivers sustainable revenue margin and customer value in a global multicultural environment.

What youll do

1. Market and Customer Insight

• Build a deep understanding of the global market for advanced cooling AI infrastructure (hyperscalers colos micro-DCs OEMs integrators telcos enterprises).

• Conduct regular interviews with strategic customers partners and channels to understand AI density roadmaps cooling strategies constraints and buying criteria.

• Analyse competitors (tanks racks CDUs integrated micro-DCs) and adjacent technologies identifying differentiation and white spaces for the product line.

2. Product Strategy Roadmap and Portfolio Management

• Define and maintain the product line vision and multi-year roadmap for high-density racks and associated options (CDUs manifolds power integration enclosures services).

• Decide on new products variants and cost-down initiatives balancing performance density cost sustainability and time-to-market.

• Align the product line roadmap with company strategy sales priorities strategic partnerships and industrial capabilities in close collaboration with CPO and Engineering.

3. Business Case and P&L Ownership

• Own the P&L of the product line: build and update business cases set volume and margin ambitions and track performance versus plan.

• Define pricing structures (per rack options services) and discount frameworks with Finance and Sales ensuring margin discipline in a high-CAPEX B2B context.

• Monitor revenue gross margin mix and pipeline; propose and drive corrective actions (portfolio pricing cost go-to-market) when targets are at risk.

4. Cross-Functional Leadership and Execution

• Lead cross-functional product line forums bringing together Sales Engineering Supply Chain Manufacturing Quality Sustainability Compliance/Certification Maintenance and Support.

• Negotiate priorities and trade-offs (features cost lead time density targets) with these teams ensuring clarity of requirements and realistic commitments.

• Act as the single accountable owner for key product decisions and as the main escalation point for issues impacting the product line.

5. Product Definition and Lifecycle Management

• Translate market and customer insights into clear product requirements: thermal and power envelopes (e.g.kW/rack) AI server types and form factor fluid types materials serviceability safety certification and integration constraints.

• Own the full lifecycle: introduction growth maturity and end-of-life including SKU/option strategy complexity control and migration paths to new generations.

• Ensure product documentation (spec sheets integration guides TCO/value tools) accurately reflects capabilities and constraints.

6. Sales and Go-to-Market Support

• Support Sales and Technical Sales Specialists on deals: positioning vs competition solution configuration trade-off discussions (density vs redundancy CAPEX vs OPEX cooling architecture choices).

• Contribute to launches major bids and strategic partnerships by preparing product value propositions reference architectures and customer-facing presentations.

• Train and enable channel partners and key accounts on the product line with Product Marketing.

7. Governance and Reporting

• Report product line performance and major risks/opportunities to the CPO and leadership team.

• Prepare and defend investment proposals (new SKUs industrialisation cost-down tooling NPI) in portfolio/governance forums.

• Ensure decisions are data-driven and aligned with the companys scaling priorities.

Advanced Liquid Cooling and AI Power Density Specific Competencies

• Solid understanding of liquid cooling technologies for IT:

  • Coldplate design basics (materials internal channels pressure drop fouling manufacturability).

  • Manifold and hose systems quickcouplings leak prevention and serviceability concepts.

  • CDUs secondary loops and their impact on rack design and facility infrastructure.

  • Comparative view of different cooling technologies in terms of PUE rack density reliability and TCO for AI workloads.

• Ability to reason about very high energy density racks (hundreds of kW to 1 MW per rack):

  • Electrical design implications (high-current busways redundancy safety).

  • Mechanical/thermal design impacts (flow rates ΔT pump and CDU sizing dry coolers/chillers water temperatures heat reuse).

  • High-performance networks (Infiniband UltraEthernet) design installation commissioning.

  • Operational aspects (commissioning service fluid handling monitoring safety procedures).

• Familiarity with industry standards and guidelines: ASHRAE liquid-cooling recommendations OCP/OCP-Ready DLC specs pressureequipment and safety norms and vendor reference architectures for GPU clusters and AI superpods.

• Ability to use thermal and TCO models (often built with Engineering/Finance) to quantify trade-offs between different cooling architectures and deployment patterns for high-density AI customers.

• Credibility and comfort engaging with datacentre operators facility engineers and AI infrastructure architects as the high-density rack product lines expert voice on cooling density and end-to-end datacenter integration.
  

What youll need

• 5 years in product management or product line management of complex technical hardware or infrastructure solutions; 10 years total experience strongly preferred.

• Demonstrated experience in one or more of: DLC datacentre equipment high-density racks HPC/AI infrastructure power and cooling systems or similar.

• Clear track record of responsibility for product financials (revenue margin pricing) and successful product launches in a scaling company.

• Experience working cross-functionally with Sales Strategic Partnerships Engineering Supply Chain Manufacturing Quality and Support in a hardware/industrial environment.

• Masters degree in Engineering Mechanical/Electrical Engineering Computer Science or related technical field.

• Additional business or management qualification (e.g. MBA or equivalent) is a plus.
  

What we offer

• Attractive compensation package reflecting your expertise and experience.

• Restaurant Pass.

• Private Health Insurance.

• Languages classes (English).

• A healthy work environment with fresh fruits to energise and an on-site gym for active breaks.

• A great work environment characterized by friendliness international diversity flexibility and a hybrid-friendly approach.

• Youll be part of a fast-growing scale-up with a mission to make a positive impact offering an exciting career evolution.
